Research interests

Qixiang CHENG received the Ph.D. degree from the University of Cambridge, Cambridge, U.K., in 2015, researching InP-based photonic integrated circuits for optical switching. He was a Research Scientist with the Lightwave Research Laboratory, Columbia University, New York, NY, USA, where he led the research effort in silicon photonic device design, layout, packaging and testing. He was heavily involved in nation-wide projects funded by ARPA-E, NSF, and DARPA in the US. He recently returned to the University of Cambridge as a University Lecturer and his current research focuses on developing system-wide photonic integrated circuits for optical communication, sensing, and optical computing applications, exploiting a number of photonic integration platforms, including InP, silicon, as well as Si-InP, Si-SiN, and photonic-electronic hybrid integration schemes. He currently serves as a committee member for OFC, CLEO-PR, ECIO, and Photonics West, and he is a guest editor for APL Photonics. He is an author of in excess of 80 refereed journal and conference papers, including 22 invited papers.
